Indonesian president Joko Widodo on Friday called for police restraint and promised an investigation into the deaths of two students, killed while taking part in protests that have spread to become the country's biggest in decades.The protests, against new laws, began on Monday and have turned violent in several places with more than 300 hurt in Jakarta alone, prompting calls from Amnesty International for an investigation into what it called "massive" aggression by police, who have fired tear gas and used water cannon.

The two dead university students, both men, were part of a rally on Thursday in Kendari on the island of Sulawesi.
